I started these beauties a little to early this year and actually worried they were getting root bound in the greenhouse while we waited for spring frost's to pass...They got a little leggy but held in there. I was able to get them into the garden about a month ago. Planting started early this year due to a warmer than usual Spring.
They've filled in beautifully, and have really added a vibrant interest to the flower bed. Nasturtiums are easy-to-grow annuals whose leaves and flowers are not only beautiful but edible, as well!
